15 Claims.

This invention relates to racks for supporting yarn packages such asbobbins or spools, with or without cones or other core members, andparticularly to the type of rack which normally consists of a supportprovided with perpendicularly disposed pins or posts arranged inrelatively spaced predetermined order afiording clearance between theyarn packages respectively mounted on the posts.

Some of the objects of the present invention are, to provide a rack ofrugged durable construction and light of weight having the postspermanently secured thereto; and to provide such a rack which isparticularly adapted for use in connection with braiding machinery tofacilitate the handling of yarn packages.

With these and other objects in view, which will become apparent fromthe following detailed description of the illustrative embodiments ofthe invention shown in the accompanying drawings, my invention residesin the rack having the novel elements, features of construction andarrangement of parts, as hereinafter more particularly pointed out inthe claims.

In the accompanying drawings:

Fig. 1 is a perspective view of a rack constructed in accordance withthe principles of the present invention;

Fig. 2 is a transverse sectional elevation taken on the line 22, Fig. 1;

Fig. 3 is a plan view;

Fig. 4 is a fragmentary sectional elevation taken substantially on theline 4-4, Fig. 3;

Fig. 5 is a fragmentary plan View of my novel rack and shows a modifiedform of spool supporting post and the manner in which the spool is heldthereby; and

Fig. 6 is a transverse sectional elevation taken on the line 6-6, Fig.5.

The rack primarily comprises a skeleton frame 1 having a plurality ofrelatively spaced posts 2, 2, cast or otherwise formed homogeneouslyintegral and in one piece with the frame, the whole of the structureincluding the frame and the posts being composed throughout of lightweight relatively tough material, such for example as aluminum, itsderivatives or equivalents.

The skeleton frame, in its preferred form, is of rectangular contour andcomprises longitudinally extending side bars or members 3 and 4respectively and a central longitudinally extending bar member 5,integrally connected by transversely extending end bar members 6 and 7respectively and by a plurality of intermediate transversely 55extending bar members 8, 8 and 9, 9 respectively.

The transverse bar members 9, 9 are disposed adjacent and parallel tothe end bar members 6 and '7 respectively and are connected thereto byshort longitudinally extending bar members 10, 10.

The posts 2, 2, in the preferred form of the invention, are arranged inlongitudinal and transverse rows with a post disposed at theintersections of each of the transverse members 8, 8 and 9, 9, with thecenter line of the central longitudinal member 5 and with parallel linesdrawn through the centers of the intermediate longitudinal bar members10, 10.

Each post 2, in the preferred form of the invention, is of cruciformcross section and comprises four substantially perpendicular ribs 11, 11disposed at ninety degrees apart, circumferentially of the post,alternating with substantially semicircular grooves 12, 12.

The outer edges or surfaces of the ribs 11, 11 taper inwardly from thebase of the post to the top thereof where the oppositely disposed ribs11, 11 are joined by and blend into a substantially semi-spherical topsurface 13 into which the bases of the grooves 12 also blend.

Each post 2 is provided with a base 15, in the present instance ofcircular form, from the top surface of which the ribs 11, 11 and grooves12, 12 of the posts 2, 2 extend.

The outer surfaces of the ribs 11 form bearing surfaces for engagementwith the wall of the bore or central opening of the core member 14 ofthe bobbin or spool mounted on the post, with one end of the core memberresting on the flat base 15 of the post.

In the present case the top surfaces of the post bases 15 are alldisposed in a single plane which preferably is coincident with theplanes of the top surfaces of the longitudinal and transverse barmembers 3, 4, 5, 6, '7, 8 and 9, providing a smooth top on the frame.

The end and side bar members 3, 4, 6 and '7 are relatively deeper thanthe intermediate longitudinal and transverse members 5, 8, 9 and 10 butin each instance these members are of a substantially ellipticalcross-section having substantially semi-circular top and bottom surfaces16 and 1'7 respectively connected by straight or slightly curved sidesurfaces 18 and 19; and the outer edges of the circular post plate-likebases 5 15, which extend laterally beyond the side edges of the barsfrom which the posts project, are rounded as are the corners of theskeleton frame and the corners where the various intersecting membersjoin with each other, all with a view of 110 eliminating any and allsharp edges and corners which could catch and injure the yarn or threadswound on the bobbins or spools supported on the rack.

Fig. 5 of the drawings illustrates a modification of the postconstruction wherein the post 211 is provided with one or moreoppositely disposed pairs of grooves 12a, 12a for receiving bowed legs20, 20 of an inverted U-shaped spring 21, the leg connecting portion 22of which rests on the top curved surface 13a of the post 2a and issecured thereto by a screw 23. This construction is adaptable for firmlysupporting bobbins or spools on the rack wherein the bore of the bobbinor spool by wear or by being in some manner slightly larger than thestandard size, which snugly and firmly fits the posts 2, would not fitthe posts 2 closely enough to prevent looseness therebetween.

The rack in either case with the homogeneously integral posts thereonmay be cast in one piece, in the old well known manner in sand flasksbut preferably is produced by die casting, whereby all the edges andsurfaces will be smooth Without necessitating grinding or buffing toremove fins or roughness as produced by the sand mold process.

Of course, the rack device specifically shown and described can bechanged and modified in various ways without departing from theinvention herein disclosed and hereinafter claimed.
